Guidance on Invasive Non-Native Species

General

Invasive Non-Native Species (INNS) are those not naturally occurring in specific regions in the UK (non-native) that have been introduced by the actions of humans and rapidly spread, out-competing native species (invasive). Only those that have serious negative impacts on our native species, our health or our economy are considered to be INNS.

INNS and the Thames

INNS are a problem for the Thames and its surroundings with established INNS in the river, on its banks and on nearby land.

Why are INNS a problem?

INNS are estimated to cost the British economy over £1.7 billion every year.

What are the PLA doing?

The PLA are co-ordinating the formation of a Thames Vision INNS Working Group. It is planned that the Group will produce a Thames INNS Strategy from which an Action Plan will develop to achieve interim targets that will contribute towards the two Vision priority actions to

"improve biodiversity of sites recognised for their wildlife interest and the connections between them" and "improve water quality by a range of measures including reduced litter in the river".

This should help us collectively achieve the Vision Environment and Heritage Goal

"The river the cleanest since the Industrial Revolution with improved habitats and awareness of heritage"
